ADVERTISEMENTS

They say "Nothing succeeds like excess," so you can stand some more about Darwin, right? Brian Switek, in a fine Darwin Day article (that I had only a minor quibble with), brought up this quote from Darwin in Animals and Plants Under Domestication:

Some authors have declared that natural selection explains nothing, unless the precise cause of each slight individual difference be made clear. If it were explained to a savage utterly ignorant of the art of building, how the edifice had been raised stone upon stone, and why wedge-formed fragments were used for the arches, flat-stones for the roof, &c.; and if the use of each part and of the whole building were pointed out, it would be unreasonable if he declared that nothing had been made clear to him, because the precise cause of the shape of each fragment could not be told. But this is a nearly parallel case with the objection that selection explains nothing, because we know not the cause of each individual difference in the structure of each being.

Now, where have I heard such an "objection" before?

Q. And I'm correct when I asked you, you would need to see a step-by-step description of how the immune system, vertebrate immune system developed?

A. Not only would I need a step-by-step, mutation by mutation analysis, I would also want to see relevant information such as what is the population size of the organism in which these mutations are occurring, what is the selective value for the mutation, are there any detrimental effects of the mutation, and many other such questions.

- Michael Behe, testifying at the Kitzmiller v. Dover Area School District case

The truly disingenuous part of Behe's evasion, when presented with massive amounts of scientific work on the evolution of the immune system, resides in the fact that none of the ID advocates, including Behe, will (except in friendly religious settings) even venture a guess at the identity of the supposed "Designer," much less suggest a step-by-step explanation of how he, she or it created the system and inserted it in some early form. In short, they demand not just unreasonable detail, as Darwin pointed out, they apply a double standard when it comes to the level of evidence they themselves have to produce.

As always, Darwin was way ahead of the creationists.
